[quote="guerrero25"]Because of vermin’s ability to adapt to pesticides, pesticides become ineffective after several years, and chemical companies have to develop new pesticides regularly. A new pesticide that proved highly effective against most species of vermin was developed recently with a unique chemical composition to which vermin will not be able to adapt. Clearly, the vermin problem for most farmers has been solved once and for all.
The argument above depends on which of the following assumptions?
(A)The new pesticide is cheaper than any pesticide previously developed.
(B)No other chemical company will develop a similar pesticide.
(C) No chemical company previously made erroneous claims about having developed pesticides that preclude the possibility of vermin adapting to them.
(D)Vermin are the most serious threat to crops.
(E)The new pesticide will be priced so that most farmers can afford it.
Premise 1: Because of vermin’s ability to adapt to pesticides, pesticides become ineffective after several years, and chemical companies have to develop new pesticides regularly.
Premise 2: A new pesticide that proved highly effective against
most species of vermin was developed recently with a unique chemical composition to which vermin will not be able to adapt.
Conclusion
the vermin problem for [color=#005e20]most farmers has been solved once and for all. [/color]
from this it is clear that from Premise 2 authore is establishing his conclusion.
New pesticide highly effective and pest will not be able to adapt ----------> Most farmers' problems have been solved Just think: How author has deduce the above said argument
Assumption 1: few of the remaining species of pesticide will not atack mot of the farmers crops.
Assumption 2: Farmers can afford this new pesticide.
Now POE.
(A)
IncorrectThe new pesticide is cheaper than any pesticide previously developed. The argument never talks about price.
This is the strengthner answer chice but definitely not an assumption. Just negate the above statement. Even after negating we can see that the negated A does not shatter the conclusion
(B)
IncorrectNo other chemical company will develop a similar pesticide. Whether new compan will develop similar pesticide. It will not help conclusion in any way.
(C)
IncorrectNo chemical company previously made erroneous claims about having developed pesticides that preclude the possibility of vermin adapting to them. Lets' assume few company has made erroneous claims about having developed pesticide..... So What? not helped us in any way
(D)
IncorrectVermin are the most serious threat to crops. We are not interested in seriousness abut pests.
(E)
CorrectThe new pesticide will be priced so that most farmers can afford it.
Bingo! It matches with our assumption.
Negate E to check whether Negated E shatters the conclusion
E') The new pesticide will be priced so
high that most farmers cannot afford it.
E' shatters our conclusion
Hence
E is our answer.
